Twelfth Night (1996)

'Keats catches precisely this quality in his ode "To Autumn" where he defines the perfection of the autumn day by reminding the reader of those things that threaten it -- the hint of transience in the "soft-dying day" and in the "gathering swallows", about to depart to escape the approach of winter. And he might be describing the quality of Twelfth Night itself when he writes in his "Ode on Melancholy" that "in the very temple of delight | Veil'd Melancholy has her sovran shrine".'

-- Roger Warren & Stanley Wells, introduction to Twelfth Night (Oxford, 1994)
